This invention relates to betting apparatus for closing the clnder notch tuyres of bla-st furnaces, and has for Aits object the provision of a novel form of supporting and operating mechanism'for such apparatus.

rl'he novel torn of supporting` and operating mechanism for the bettingl bar ofthis invention is adapted to move the bar into and out of the cinder notch tuyere by a horizontal movement and means is provided for jarring` the bar when it isA being withdrawn from the tuyre so as to loosen said bar.

' In the drawings:

Figure 1 is an'elevation partlyin section showing' my improved apparatus as applied for use on a blast furnace. f

' Figure 2 is alsectional elevation of the botting` apparatus taken on the' line lll-1l ot Figure 1. 2o Referring,T more particularly to the drawings, the numeral 2 designates a section of the blast furnace wall having the cinder notch tuyre `3 cooler ala and monkey t. A betting bar A isprovided for removably closing` the opening` in the monlreycooler Ll and comprises a hollow shank `portion 5 terininating` in a tapered head portion 6. rl`he shanli to the rear of the portion 5o 5 is in the form of a solid bar I' and termiw nates at its rear end in a striking,` head 8 adapted to receive slecge hammer blows iny an en'iergency if the bar becomes stuck in the mmiliey-cooler.v

5 The hollow bar portion 5 and head 6 are formed hollow so as to permit water cooling, when desired.

rlhe bar A adapted to be supported by y suitable operating mechanism which iscarricd by an overhead supporting plate 9. rlhe plate 9 is supported by angle brackets 10 mounted on the bustle pipe 12 and bos-h bands 13 of the furnace.

n A pair or" horizontally spaced and parallel links 1A and 15 are pivotally mounted in the same vertical plane on the plate 9.

A pair or" duplicate, curved guide tracks 16 and 1'? are mounted on said plate `9 below said links. The tracks 1G and 17 are also :'50 spaced horizontally and alined vertically.

herein including.;` a monkey A pair of connecting rods 18 and 19 are provided and one end of said rods is pivotally suspended from each of the respective links 11 and 15.

The lower ends of the connecting rods 18 55 and 19 are pivot-allyconnected at horizontally spaced points tothe solid bar portion 7 of the betting bar A.

The connecting rods 18and 19 are provided with rollersy 2O and 21, respectively, Ge which are adapted to ride in the guidetracla 16 and 1T, respectively,

rEhe rollers 20 and 21 are so positioned on the rods 18 and 19 that they will'maintain the links 14 and 15 in an upwardly and rear- 65 wardly inclined position. y The tracks 1G and 17 are curvedinsuch a manner as to guide` the connecting rods 18 and 19 through a path when swung to' and from said cinder notch tuyere as will maintain said bar in a horizontal position, and also to maintain said bai-'in a iXedhoriZontal plane when entering and moving out of said tuyre.

Due to the path of travel of the rods 18 and 19 caused by the tracks 16 and 17, the links "75 14 and 15 will be forced to swing.)r` about their pivotal mountingon the overhead plate 9 so as tol forma vertically movable pivot point for said connecting' rods.

` A guide bar 25 is arranged in parallel 80 spaced relation to the plate 9 and is secured thereto. The connecting rods 18 and 19 are passed upwardly through thespace between the bar 25 and plate 9 and are thereby limited in their movement in a. direction trans- S5 versely of the plate so as to prevent displacement of the rollers 20 and 21 from the tracks.

In order to move the betting bar out of the tuyre a crank-shaped lever 26 is pivotally mountedintermediate its ends as at 27, Yon the rearmost connecting rod 18, and a cable 28 has one end connected to the rearleg of lever 26 and its other end is trained upwardly over suitable sheaves and is secured to a winch 29; n TWhen it is desired to withdraw the botting bar the winch 29 will be operated to take up the cable 28. The winch will be easily operated until the slack is taken up in the cable 28 and the lever 26 is rocked about its mount- CII ing. Therefore, considerable speed may be developed by the winch. he pull on the lever 26 as the slack is taken out of the cable 28 will cause said lever to rock about its pivotal mounting and strike the rearmost connectinqV rod so as to jar the botting bar and loosen said bar it it is stuck in the tuyre.

When it is desired to insert the betting bar after it has been withdrawn from the tuyere the winch Q9 is released and the bar descends into the tuyre by'gravity.

1t will be understood that l do not wish to be limited tothe use of the winch 29 for operating the cable 28 since various mechanisms may be substituted therefor.

Vhile l have shown and described one specilic embodiment oic my invention l do not wish to be limited thereto since. .farious modifications may be made without depart ing from the scope of my invention, as delinedin the appended claims.

I claim :v Y

l. The combination with cinder notch tuyre, oi a betting bar adapted to close said t'uyere, an overhead support, a pair of horizontally spaced and parallel links pivotally mounted in the same vertical plane on said support, a pair of curved guide tracks on said support, a pair of connecting rods having their upper ends pivotally connected to the free ends oi respective ones of said links and having their lower' ends pivot-ally connected to said betting bar at horizontally spaced points, guide-rollers on said connecting rods and mounted to travel on said tracks, said rollers being so positioned vertically on said rods as to maintain said links in an upwardly and rearwardly linclined position, and said tracks being curved so as to guide said connecting rods through a path when swung to and 'from said einde-r notch tuyere as will maintain said bar in a horizontal position, said links moving about their pivotal. mounting on said overhead support assaid connect ing rods are moved toward and away from said tuyere and thereby forming a'vertically movable pivot point for said connecting rods, means for limiting the movement of said connecting rods in a: direction transversely of said tracks to thereby prevent displacement ot said rollers from said tracks, means connected to the rearmost one o1c said connecting rods for pulling said betting bar rearwardly, and means operated by said pulling means for striking a blow against said rearmost connecting rod at the beginning oi the pulling action. i

2. The combination with a cinder notch tuyre, of abetting bar adapted to close said tuyre, an overhead support, a pair of hori- Zontally spaced and parallel links pivotally mounted in the same vertical plane on said support, a pair of curved guide tracks on said support, al pair of connecting rods having their upper VendsV pivotally connected to the free ends of respective ones of said links and having their lower ends pivotally connected to said botting bar at horizontally spaced points, guide-rollers on said connecting rods and mounted to travel on said tracks, said rollers being so positioned vertically on said rods as to maintain said links in an upward ly and rearwardly inclined position, and said tracks being curved so as to guide said connecting rods through a path when swung to and from said cinder notchA tuyre as will maintain said bar in a horizontal position, said links moving about their pivotal mounting on said overhead support as said connecting rods are moved toward and away from said tuyre and thereby forming a vertically movable pivot point forv said connecting rods, means for limiting the movement of said connecting' rods in a direction transversely of said tracks to thereby prevent displacement of said-rollers from said tracks, a crank-shaped striking lever pivotally mounted on the rearmost one of said connecting rods, a drum, a flexible member connected to said drum and said striking lever adapted to be vrapped on said drum to movesaid botting bar from said tuyere and to be unwrapped from said drum to permit said botting bar to'move by gravity into said tuyre, said lleaible member being adapted to rock said striking lever when said flexible member is wrapped on said drum so as to cause said lever to strike said bar and jar said betting bar to loosen it from said tuyre.

3. In a betting bar structure an overhead support, a pair of connecting rods depending Jfrom said support, al botting bar connected to said rods, a crank-shaped striking lever pivotally mounted on one of said connecting rods, a flexible member connected to said striking lever and adapted to be taken up to move said .betting bar out O'cperative position and to be slackened to permit said botting bar to move by gravity into operative positioinsaid flexible member being adapted to rock said striking lever when said flexible member is taken up so as to cause said lever to strike said bar and jar said bot-ting bar.

In testimony whereof, I have hereunto set my hand.
